Earlier this month, the US military said eleven vessels from the IRGCN came dangerously close to US Navy and Coast Guard ships in the Gulf, calling the moves "dangerous and provocative."
At one point, the Iranian vessels came within 10 yards of the US Coast Guard cutter Maui.
While such interactions at sea had occurred occasionally a few years ago, they had stopped recently.
Tensions between Iran and the US increased earlier this year after the US killed Qassem Soleimani, the head of Iran’s elite Quds Force, in a drone strike in Iraq.
Iran retaliated on January 8 with a rocket attack on Iraq’s Ain al-Asad base where US forces were stationed. No US troops were killed or faced immediate bodily injury, but more than 100 were later diagnosed with traumatic brain injury.
Iran's Revolutionary Guards Corps said on Wednesday it had successfully launched the country's first military satellite into orbit.
